Moving frame. In a railroad car traveling at .500 cm/s along a straight track, a head-on collision takes place between a 100-g mass moving with velocity 100 cm/s in the same direction as the train and a .50-g mass moving in the opposite direction at .500 cm/s. Both velocities are relative to the train. After the collision, in the car the ,50-g mass is at rest; what is the velocity of the IOO-g mass? How much kinetic energy has been lost?
Now describe the collision from the point of view of an observer at rest by the track. Is momentum conserved? How much kinetic energy is lost in this frame?

Superheated steam in a piston-cylinder device is initially at 200 °C, 600 kPa. Heat is removed from the system during an isobaric process until half of the mass condenses to saturated liquid
Starting from the basic principles, derive a differential equation that governs the variation of the temperature of the wire as at Function of the distance x from the extrusion nozzle. Also specify the boundary conditions.
Explain when it may be cost effective to use formal specification and verification in the development of safety-critical software systems. Why do you think that critical systems engineers are against the use of formal methods?
